About Air Knife Paper Coating Machine
The Air Knife Paper Coating Machine manufactured by Mohindra Mechanical Works is designed to apply a smooth and accurately controlled coating layer on paper and paperboard. Its air knife system uses a regulated stream of air to remove excess coating material and maintain a uniform coating thickness across the complete web width.
This machine is suitable for water-based barrier coatings, pigment coatings, starch, latex and other functional paper-coating applications.
It incorporates an automatic unwinding unit, precision coating section, adjustable air knife, multi-zone hot-air drying chamber and controlled rewinding system. PLC and HMI controls allow the operator to manage machine speed, drying temperature, web tension and coating parameters conveniently. Its heavy-duty construction provides stable, low-vibration operation during continuous production. Machine width, drying length, heating method and operating speed can be customized according to the buyers paper grade and production requirements.
